DTC, medical journals and social media

by Sally Church in Pharma Strategy Blog

Researchers at Dana-Farber Cancer Institute in Boston recently administered a survey to 348 patients with a variety of cancers. The response rate was 75%, which was a pretty good response rate. Overall, 86.2% of patients reported being aware of cancer-related...... Read more »

Homeotics, Cladistics and the Triple Emergence of Closed Hand Gaits in Descendants of an Upright Ancestor of the ApesGuest Post by Aaron Filler, MD, PhD, FRCSIf an upright bipedal ancestor evolved first, why would three of its descendant lineages abandon orthograde posture and restore quadrupedal gaits to their repertoire?Firstly, we don't have to have an answer as to why it happened if that is indeed what happened. If it occurred, then it occurred whether or not we have proposed and accepted a ........ Read more »

Autobiographical and nonautobiographical memory functioning in PTSD

by William Lu in The Quantum Lobe Chronicles

Posttraumatic stress disorder (PTSD) is a debilitating disorder characterized by altered memory functioning including the unintentional reliving of the traumatic experience. This feature of the disorder has been the focus of most PTSD studies, however rarely has there been an investigation on the aspect of disturbed intentional recall within the PTSD patient population. Jelinek et al. decided to address the paucity in this area of research by first clarifying central qualitative and quantitative........ Read more »

The Social Side of Eating

by Christie Wilcox in Nutrition Wonderland

Much of nutrition focuses on the individual. You are responsible for picking the right foods, eating healthy, exercising, and doing what’s best for your body. Nutrition consultations are one-on-one, focused on the single person’s dietary needs and deficiencies. And that’s great – if you’re single, have no friends, and live and work by yourself. But the truth is most of us are a part of a larger network of people, whether it be because we’re married, work in a ........ Read more »

The new naturalists?

by Daniel in Ego sum Daniel

Some time ago I watched a documentary called Lord of the Ants (clips available online) about the brilliant Ed O. Wilson, a born Naturalist whom I've also had the pleasure of hearing in person, and I was struck by his enthusiasm for natural history and the traditional exploratory naturalist work. It fed my imagination and made me think about my own work as a biologist. I'm probably as far away as you can come from a field biologist, working as I do with online genome databases and DNA sequences,........ Read more »

Those Cheating Testicles, or Who's Your Baby?

by Eric Michael Johnson in The Primate Diaries

Benjamin Franklin once quipped, "Where there's marriage without love there will be love without marriage." His affairs are well known in American history, however this founding father may have been stating a truth extending to evolutionary history as well.

Christopher Ryan (author of the forthcoming Sex at Dawn) offers some thoughts on the role of novelty in the sex lives of our favorite primate. He suggests that men are drawn to variety in sexual partners while women are drawn to variety in ........ Read more »

Podcasting in Education

by Kristen DiCerbo in Connections Research Blog

Podcasting is a relatively new addition to many classrooms and as such, research on it is somewhat limited. McGarr recently reviewed existing studies and identified three types of usage:

Substantial – delivering full lectures
Supplemental – reviewing and/or synthesizing material
Creative – having students create podcasts

Podcasting is interesting to me because although it uses new technology, it largely [...]... Read more »

Schizophrenia: The Mystery of the Missing Genes

by Neuroskeptic in Neuroskeptic

It's a cliché, but it's true - "schizophrenia genes" are the Holy Grail of modern psychiatry.Were they to be discovered, such genes would provide clues towards a better understanding of the biology of the disease, and that could lead directly to the development of better medications. It might also allow "genetic counselling" for parents concerned about their children's risk of schizophrenia.Perhaps most importantly for psychiatrists, the definitive identification of genes for a mental illness w........

Poliovirus type 2 returns

by Vincent Racaniello in virology blog

The global battle to eradicate poliomyelitis is already 9 years behind schedule. To make matters worse, type 2 poliovirus, which was declared eradicated in 1999, has returned.
There are three serotypes of poliovirus, each of which causes poliomyelitis. The vaccine used by WHO in the global eradication effort is a trivalent preparation comprising all three serotypes. [...]... Read more »

Unique Urine Fingerprints

by sciencebase in Sciencebase Science Blog

For decades, the word “fingerprint” has been used to denote a set of unique characteristics, whether literally the complex patterns of arches, loops, and whorls on one’s fingertips or entirely figuratively and more recently, the notion of a genetic fingerprint based on an analysis of an individual’s DNA sequence.
Most recently though, scientists have turned to [...]Unique Urine Fingerprints is a post from: Sciencebase Science Blog

Health Insurance for All – A Weighty Issue

by Shaheen Lakhan in Brain Blogger

The prospect of universal health coverage for all Americans is weighing heavily on lawmakers right now. But, if the current proposals pass Congress, Americans may be looking at an even “weightier” problem. New economic research suggests that having health insurance actually makes people fat, and that, in turn, increases health care spending.
A working paper recently [...]... Read more »

Is Throwing a Curveball Dangerous to our Youth Baseball Pitchers?

by Mike Reinold in

  Over the last few weeks, there has been some debate regarding the release of two recent studies that showed that curveballs may not be as damaging to our youth baseball pitchers as we had once thought. I tried to let this die down a bit before discussing it, as the general press really picked up on this and started a debate with absolutely no medical background.  The New York Times discussed this recently and  I even saw a couple of sportscasters on ESPN discussing this on TV........

Unconscious Cognition 2-Going Beyond Zero Awareness

by Varun in Wissenschaft

In the first part "Unconscious Cognition 1- Simple Dissociation", we established two sets of assumptions for the zero awareness criterion. The exhaustiveness assumption where the direct measure D is a strictly monotonic function of conscious information c and a weakly monotonic function of unconscious information u and the indirect measure I is a weakly monotonic function of both c and u. Under these conditions, D(c,u)=0 necessitates c=0 and I(c,u)0 implies I(0,u)0 which in turn i........ Read more »

Inflammation, microRNA, and cancer

by Charles Daney in Science and Reason

If there's just one single point worth making about the biology of cancer, it would have to be "it's complicated".Cells in general, and animal cells in particular, are extremely intricate Rube-Goldberg-like mechanisms. Their correct functioning depends on the integrity of 20,000 or so genes (in the case of humans), and at least 5 times as many proteins whose form is specified by the genes. Damage to even one of a few thousand important genes can put a cell on the road to becoming cancerous. So t........ Read more »

Facial emotional expressions are not universal

by Christian Jarrett in BPS Research Digest

From the Bushmen of the Kalahari to the Kalaallit of Greenland, you'll find that people everywhere frown in frustration and smile in delight. Or will you? The universality of human emotions and their expression in the face has become widely accepted in psychology. At the vanguard of this perspective is pioneering psychologist Paul Ekman, the co-creator of the facial action coding system (FACS) - a way of categorising and interpreting facial expressions according to which muscles are tensed.

Christianity as a civilizing force? The case of Ghanaian women

by Tom Rees in Epiphenom

In the comments, Dheeraj has been arguing for Christianity as a civilizing force in human society. Now that's a big question with a lot of arguments on either side. But here's a new study that gives an interesting angle.The researchers studied women from the Kassena-Nankana of northern Ghana, going there first in 1995, and then back in 2003. What they found was that many of the people in this remote region are changing religions - they're abandoning traditional beliefs in favour of Christianity......... Read more »

Risk management: core competence?

by Jan Husdal in

Is risk management overlooked as an important source of competitive advantage?
